Australian spies have confirmed Bashar al-Assad regime used chemical weapons on civilians.
Australia will now be standing alongside the United States on military strikes on Syria after the revelation.
Foreign Minister Bob Carr, attending the G20 leaders forum in Russia, revealed Australia's spy agencies had its own intelligence, which confirmed the Assad regime was behind the chemical bombing of its own citizens.
According to news.com.au, he said the United States like others wanted a negotiated peaceful outcome to the Syrian crisis.
He however added that any use of chemical weapons had to be met with an appropriate reaction, as defined by the US military.
Carr did not elaborate whether the raw data analysis, understood to include soil and body samples taken at sites in Damascus following the bombings on August 21 which killed almost 1500 people, meant Australian spooks had agents active on the ground in Syria, the report added.
